Composition a base of nitroprusside and its application to the detection of the ketonic

摘要

P the invention relates to a composition of the test for the detection of ketones. / p & & p & the composition of the test of the invention contains a nitroprusside associated with at least one inorganic salt of a metal such as magnesium and calcium. At least one primary amine can be added to this combination. This composition is advantageously incorporated in a support such as a matrix or a panel in order to form a device of the test. The metal salt stabilizes nitroprusside in solution in an alkaline ph, which therefore allows a method of production by straightforward immersion, it promotes the ionization of the ketone bodies, which shortens the reaction time and it stabilizes the complex chromophore resulting; this latter is also stabilized by the primary amine. Application to the field of diagnostic / p
